To aZZ ZU/LO'IID it may concern.-

Be itknown th atl, GEORGE W. EVERETT, a citizen of the United States,residing in the city, county, and State of New York, have inventedcertain new and useful Improvements in Swingin g Window-Sashes, of whichthe following is a specification.

My invention relates more particularly to window-sashes which swing andslide and provides an organization in which the upper and lower slidingsashes of a window may readily be brought to such position that theouter faces of the glass may be conveniently reached for cleaning fromthe interior of the room and which permits of the arrangement of thelower sash in such way as to aiford the adjustment and ventilation thatmay be had with an ordinary non-sliding sash turning upon a horizontalaxis, while at the same time protecting the joints,so that there is evenless liability of the entrance of cold air, rain, or snow than there iswith an ordinary well-fitted sliding sash.

I am aware that heretofore sliding sashes have been made that have thesame capacity for manipulation or adjustment as is afforded bymyinvention; but all such organizations, so far as I know, differradically from that herein described.

In the accompanying drawings, Figure 1 is a front elevation of awindow-frame and sashes, partly broken away or in section, constructedand equipped in accordance with my invention. Fig. is a verticaltransverse section on the line 2 2 of Fig. 1; Fig. 3, a similar sectionshowing the sashes in different position; Fig. i, a detail sideelevation of the lowerend of a removable parting-strip, and Fig. 5 anelevation of the front or outer face or edge of the same strip. Fig. 6is a detail sectional view, on an enlarged scale, showing the pivotalmounting of the sash.

The window frame or casing A may be of ordinary construction and isprovided with parting-strips at, front stops A and back stops d formingthe channels in which the upper and lower sashes run. Each sash c011-sists of three parts, a central rectangular part, carrying the glass,and side strips 13 B, running in the channels in the frame and withwhich the sash-cords C are connected. The central section it, which. forconvenience will be called the sash, is carried by the side strips Bthrough the medium of pivotal connections D, upon which the sash mayswing. These pivots are of a special construction and will be describedin detail later. If at each side of the window the stops A A andparting-strip A do not project from the jamb or frame into the path ofthe swing-sash, the sash could be swung about its pivot in eitherdirection, in or out. Such a general arrangement is old. It, however,has the disadvantage that the joints between the sash proper and sidestrips are not covered or protected from wind, rain, &c. To effectuallycover and protect these joints, so that the window shall be in allrespects even better than an ordinary well-fitted sliding. sash, I makethe parting-strips A of such width as to project well over, cover, andprotect them.

To provide for the swinging of the sash when desired, the parting-stripsare made in whole or in part removable, and means are provided forlocking them when in position in the frame. Thus in the drawings theparting-strips are at about the point where the rails of the upper andlower sashes meet divided by a double inclined or dovetail cut. (Shownin Fig. l by the dotted lines a.) The parts of the strips below this cutmay read ily be removed from their grooves or seats in the sash-frame.Upon the sill at each side, at the bottom of the groove, is a block F,having an inclined face f, upon which the inclined end of the stripseats, and a notch f toengage a pivoted latch f mounted on the strip.Normally the removable parts of the strips are locked in position. lVhenit is desired to swing the sashes, the latches are disengaged from theblocks and the lower parts of the strips removed. As seen in Fig. 2, thelower sash may then be swung to bring the outer face of the glass towardthe interior of the room. In Fig. 3 the lower sash is shown pushed upand the upper sash drawn down and similarly swung upon its pivots. Ofcourse any means of holding the removable parts of the strips inposition may be adopted, and some means is of course desirable. It isapparent that such a window is even tighter than one of ordinaryconstruction. To each edge of the sash is attached a plate d, having apivot pin or trunnion cl, that when the sash is in the normal verticalposition inclines downwardly. On the side strip is a plate D, having anelongated opening in which the trunnion has its bearing. The inner edgeof this plate at the bottom of such opening or all around it ischamfered or inclined at the same angle as the inclination of thetrunnion, and a cavity is formed in the strip opposite the opening inthe plate. The purpose of this construction is that the weight of thesash by reason of the inclination of the trunnions and their bearin gsshall draw the strips against the sides of the sash and make atightjoint. The pivotal connections are shown applied at about the middle ofthe sash. They might be placed elsewhere, and in some cases it would bedesirable to place them at or near the upper or lower edges of thesash-as, for instance, in the case of cellar or other windows, wherethere is no space or free way for part of the sash to swing outwardly.

I claim as my invention 1. The combination of a window frame or casing,a sash having a central swinging portion and side pieces upon whichit ispivoted, and pivotal connections between the side pieces and sash,having downwardly-inclined bearing-faces when the sash is in the normalposition.

2. The combination of a window frame or casing, a sash having a centralswinging portion and side pieces upon which it is pivoted, pivotalconnections between the side pieces and sash, having downwardly-inclinedbearing-faces when the sash is in the normal position and removablestrips overlapping the joint between the sash and side pieces.

3. The combination of a window-frame, the front stop, sash side piecesrunning in the channel back of the stop and projecting beyond the faceof the stop, a sash, pivotal connections between the sash and sidepieces having downwardly-inclined bearingsurfaces, and removable stripsback of the sash overlapping the joint between the sash and its sidepieces.

4. The combination of a window-frame, its front and back stops,intermediate partingstrips divided at, or about at, the meetingrails ofthe two sashes and having their lower portions removable and replaceableat will, the u pperand lower sashes having side pieces running in thechannels in the frame and projecting beyond the faces of the stops butterminating inside the faces of the partingstrips, pivotal connectionsbetween the sashes and their side pieces having downwardly-inclinedbearing-surfaces when the sashes are in the normal vertical position.

In testimony whereof I have hereunto sub scribed my name.

GEORGE w. EVERETT.
